In countries where there are very elevated mountains, it is not necessary to wait for the revolution of the year to observe the effects of different degrees of temperature. Meteoro- logists have demonstrated that in every country the atmosphere becomes colder as we ascend, until the cold reaches a great intensity. As a consequence of this law of the atmosphere, a traveller, by merely ascend- ing the slopes of a mountain towards its higher regions, will pass through every va- riety of climate in the successive gradations of the elevation. The stupendous range of the Himalayas in Asia, and the Andes in South America,> present, in one continuous surface, all the climates of the earth, from the glowing vegetation of the tropics to the eternal snow of the poles. The plains around the base of such mountains, and the slopes on their different spurs, are covered with the
